Effective Field Theory of Random Quantum Circuits [PDF]
Entropy, 2022 Quantum circuits have been widely used as a platform to simulate generic quantum many-body systems. In particular, random quantum circuits provide a means to probe universal features of many-body quantum chaos and ergodicity.

Effective field theory for chaotic CFTs
Journal of High Energy Physics, 2018 We derive an effective field theory for general chaotic two-dimensional conformal field theories with a large central charge. The theory is a specific and calculable instance of a more general framework recently proposed in [1].

Firewall from Effective Field Theory [PDF]
Universe, 2021 For an effective field theory in the background of an evaporating black hole with spherical symmetry, we consider non-renormalizable interactions and their relevance to physical effects.

Effective field theory for leptoquarks
Journal of High Energy Physics, 2023 Leptoquarks enter in several extensions of the Standard Model as possible solutions to a number of observed anomalies. We work within the soft-collinear effective theory framework to present a detailed analysis of the decay rates of the three leptoquarks

Dark sector effective field theory
Journal of High Energy Physics, 2023 We introduce the effective field theory of two different light dark particles interacting with the standard model (SM) light states in a single vertex, termed dark sector effective field theory (DSEFT). We focus on the new light particles with spin up to

ALPs effective field theory and collider signatures [PDF]
European Physical Journal C: Particles and Fields, 2017 We study the leading effective interactions between the Standard Model fields and a generic singlet CP-odd (pseudo-) Goldstone boson. Two possible frameworks for electroweak symmetry breaking are considered: linear and non-linear.

Dilaton Effective Field Theory
Universe, 2022 We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure.

Baryonic effective field theory for light hypernuclei [PDF]
EPJ Web of Conferences, 2022 Light hypernuclei containing one or two Λ baryons are the subject of an ongoing experimental campaign aiming to study the spectrum of these systems, as well as the 2 and 3-body interaction between Λ hyperons and nucleons.

Small-x factorization from effective field theory
Journal of High Energy Physics, 2023 We derive a factorization theorem that allows for resummation of small-x logarithms by exploiting Glauber operators in the soft collinear effective field theory.

An effective field theory of magneto-elasticity
SciPost Physics, 2022 We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials.
